MACHINING TIPS: Critical Aspects to Grinding - Surface

Jan 11, 2017· A grinding wheel with a rougher grit will remove more material per pass, but the result is a rougher surface finish. A finer grit will remove less material per pass, but give you a smoother finish. The drawback to a finer grit is the potential for clogging of the wheel and over heating of the plastic which results in burnishing or burning of

Effect of cutting parameters on the dimensional accuracy

Abstract. In the machining operations, final surface finish and dimensional accuracy are the most specified customer requirements. Hard turning machining operation using cubic boron nitride tool as an alternative of grinding process is a type of turning operation in which hardened steel are machined with the hardness greater than 45 HRc.
